The Vornado Tower Circulator offers a more effective way to circulate air with V-Flow™ Circulation. Uniquely contoured air outlets create a wide span of constant airflow, without the need for oscillation. Typical tower fans oscillate due to limited range of air movement. You feel the airflow for only seconds at a time. With V-Flow™ Circulation, a high volume of air is continuously moving throughout the room, creating quiet, comfortable Whole Room Circulation. Vornado has eliminated the wobbly base found on oscillating tower fans in favor of a solid and sturdy system that stands the test of time.
